Nice work! Don't know why people knock these flat diodes. They're not hard to work with.

i thought this little trick might come in handy if you don't use a PCB board to make a battery contract. http://laserpointerforums.com/f51/ho...ial-70623.html

Default Re: My D.I.Y Flat Diode Build (PICS)

so i`ve ran the diode with a duty cycle of 30sec @ 297ma , the beam was very clean , instant burning & it got barely warm to touch ...the 317 which was not sinked was alot hotter to touch than the sinked diode ..i was using 2x 18650`s .

the other 317 i`ve built max`s out just under 400ma , so i will try that later starting @ 300ma .

if some 1 could give me there professional opinion on the limitations of these diodes it would be greatly appreciated .

cheers guys

absolute rookie mistake ..R.I.P 1st flat diode ...16v dump from the cap !! so i`ve just picked up another and going to replace .....also i`ve now got 1 of the 3pin flat diodes for the nxt build ...tested it @ 250ma , works very well , i`ve got to machine the sink on this because its a stupid design .....
